4 Revolutionary fuel efficiency. At Volvo we know that fuel efficiency is one of your highest priorities. That’s why our engineers are constantly developing clever innovations to make equipment more fuel efficient. Our unique, award-winning OptiShift technology – which reduces fuel consumption by up to 18% and increases machine performance – is a prime example of this. Reverse By Braking (RBB) The RBB function senses the loader’s direction and slows the machine when the operator wants to change direction by reducing engine rpm and applying the service brakes automatically. This increases operator comfort and reduces stress on the drivetrain – extending component life. Eco pedal Volvo’s unique eco pedal applies mechanical push-back force when the accelerator is used excessively and engine rpm is about to exceed the economic operating range. This encourages the operator to ease off the throttle, reducing fuel consumption. Intelligent hydraulics Volvo’s load-sensing hydraulics supply power to the hydraulic functions according to demand, lowering fuel consumption. The powerful system ensures fast response for shorter cycle times while delivering smooth operation through superior control of both the load and attachment.

5 OptiShift Volvo’s optional OptiShift technology combines the company’s patented Reverse By Braking (RBB) technology and a torque converter with lock-up. Lock-up creates a direct drive between the engine and transmission – eliminating power losses in the torque converter and reducing fuel consumption by up to 18%.

6 Volvo cab The spacious ROPS/FOPS certified cab features ergonomically placed controls, all-around visibility and ample storage. With effective sound insulation, low internal noise levels and vibration protection, operators will experience a comfortable and productive work shift.

7 Comfort unlocks productivity. Volvo’s industry-leading cab has been designed with the operator in focus – providing a spacious, safe and quiet environment that’s perfect for optimizing productivity all day long. With all-around visibility and a comfortable seat, step inside and see the difference this premium working environment will make to your performance. Single lever control For ease of operation, the optional, multi-functional joystick gives the operator simultaneous and precise control of the hydraulic functions. Forward, reverse and kick-down functions are also included on the console. Cab air filter The cab air intake is located high on the machine, where air is cleanest. The easy-to-replace pre-filter effectively separates coarser dust and particles before the air passes through the main filter and finally enters the cab. Volvo’s industry-leading design allows 90% of the cab air to be recirculated through the main filter for continuous dust removal. Information panel The display clearly presents the operator with vital machine information including fuel levels and warning messages – ensuring optimal operation. From the operator seat, basic configurations and tests can be performed via the panel – which is easy-to-read even in bright sunlight. Safe access Easily and safely access the cab via a three-point access ladder with anti-slip steps. Ideally positioned, sturdy handrails and a wide door frame with a 95° opening angle further increase operator safety and comfort – as do the optional remote door opener and cab entrance light.

8 Powerful. Durable. Reliable. Featuring a premium Volvo Tier 4 Final/Stage IV engine and perfectly matched drivetrain and hydraulics, the L110H and L120H wheel loaders deliver the power, productivity and reliability you expect from Volvo. Whether you’re working in the quarrying, material handling, recycling or any other application, these durable machines won’t let you down. Maintaining a smooth operation Enjoy peace-of-mind for maximum machine uptime with the rear axle design. The sealed oscillation pins cradle keeps the grease in and the dirt out, keeping components greased for up to 8,000 hours so you can rely on reduced overall service time and costs. Volvo engine Featuring advanced technology and built on decades of experience, the powerful, new Volvo engine meets the Tier 4 Final/Stage IV emission regulations and delivers the ultimate combination of high performance and low fuel consumption. Reversible cooling fan The hydraulically-driven, electronically controlled cooling fan regulates the temperature of the vital components. It automatically activates only when it’s needed – reducing fuel consumption and noise. The reversible functionality – which blows air in the opposite direction – allows for self-cleaning of the cooling units.

9 Powertrain The ideally-matched, all-Volvo powertrain has been built to work together in perfect harmony. The Volvo design has been rigorously tested to deliver optimized performance, high productivity, low fuel consumption and superior reliability.

10 Attachments Volvo’s wide range of durable attachments have been purpose-built to work in perfect harmony with Volvo machines. The attachments are designed as an integrated part of the wheel loader for which they’re intended – with functions and properties perfectly matched to parameters including link-arm geometry and breakout, rim pull and lifting force.
